Scleral reinforcement surgery

Surgical procedure to strengthen the sclera of the eye

Scleral reinforcement surgery is a surgical procedure aimed at strengthening the sclera, the white outer coating of the eye. This procedure is primarily used to treat conditions that lead to the thinning or weakening of the sclera, such as pathological myopia and certain degenerative diseases. The goal of scleral reinforcement is to prevent further elongation of the eye and to stabilize vision.

Indications

Scleral reinforcement surgery is indicated in cases where there is progressive myopia due to scleral thinning, which can lead to complications such as retinal detachment. It is also considered in certain cases of scleral ectasia and other degenerative conditions that compromise the structural integrity of the sclera.

Procedure

The procedure involves the placement of a reinforcing material around the posterior segment of the eye. This material can be synthetic or biological and is designed to provide additional support to the sclera. The surgery is typically performed under local or general anesthesia, depending on the patient's condition and the surgeon's preference.

Surgical Technique

The surgical technique involves making a small incision in the conjunctiva to access the sclera. The reinforcing material is then carefully positioned around the posterior pole of the eye. The material is secured in place using sutures or other fixation methods. Care is taken to avoid damage to the optic nerve and other critical structures.

Materials Used

Various materials have been used for scleral reinforcement, including:

• Autologous tissue grafts
• Donor sclera
• Synthetic materials such as silicone bands

The choice of material depends on the surgeon's preference, availability, and the specific needs of the patient.

Postoperative Care

After the surgery, patients are typically monitored for signs of infection or complications. Antibiotic and anti-inflammatory medications may be prescribed to aid in healing. Follow-up visits are crucial to assess the success of the procedure and to monitor the stability of the eye.

Complications

As with any surgical procedure, scleral reinforcement surgery carries risks. Potential complications include:

• Infection
• Inflammation
• Extrusion of the reinforcing material
• Damage to ocular structures

Prognosis

The prognosis for patients undergoing scleral reinforcement surgery varies. In many cases, the procedure successfully stabilizes the eye and prevents further progression of myopia. However, long-term outcomes depend on the underlying condition and the patient's overall ocular health.
